VIILLIAM J. ll-EACFARLAND, OF BOSTON, MASSACHUSETTS.

ARCH-SUPPORT.

Massachusetts, have invented certain new and useful Improvements in Arch-Supports,

- of which the following is a specification.

I This invention relates to arch supports for boots and shoes, and has for its object the provision-of means whereby the curvature of the support may be varied at will to accommodate the support to different arches anddifi'erent conditions. 7

The invention consists of two plates securedtogether near opposite ends and provided between the securing points with members by which the plates may be separated predetermined distances.

The invention further consists of certain novel features of construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claims hereinafter given.

Ofthe. drawings Figure 1 represents an elevation of a shoe with a portion of the upper brokenaway and showing an arch support embodying the principles of the present invention. Fig. 2 represents a plan of the same, a portion of the upper and portions of the inner sole being broken away. Fig.

3 represents an elevation of a portion 01 a shoe drawn to an enlarged scale and showing'portions in section, and Fig. 4 represents a transverse section of the support removed from the shoe, the cutting plane being on line H on Fig. 3.

. Similar characters designate like parts 0 throughout the several figures of the draw- 40" ings.

In the drawings,

he shoe is also provided with-the inner sole 13 between which and'the outer sole 11 is interposed a plate 1 1 havin superimposed thereon another plate 15. hese plates 14 and 15 are pivoted to the outer sole and heel by means of the pivot member 16 threaded to a flanged member 17 embedded in the under face of the outer sole 11. The pivot member 16 is provided with a transverse pin 16 bearing against the under surface of the plate 14 so that by turning the member 16 the plates 14 and 15 may be raised or lowered relatively to the heel 12. Near the rear end of the plates 14 and 15 these plates are Specification of Letters Patent.

provided with slots 18 concentric to the;

pivot 16 and a threaded member- 19 extends through these slots into another flanged member 20 embedded in the outer sole 14.

By looseningdw member 19 the plates. 14 and 15 may be moved together aboutthe axis of the pivot 16 and then clamped in adjusted position. It will be apparent from an inspection of Fig. 2 of the drawings that the plates 14 and 15 are of such shape as to hermit limited transverse movement about the pivot 18. The plates 1 1 and 15, are provided with an opening 21 therethrough in which tacks may be positioned during the lasting operation. The plates 14 are provided with projections 22 and 23 adapted to .bear upon the upper face of the outer sole near the (inter edge thereof.

The plates 14 and 15 are provided with -a long forward extension 24 near their inner edges and in the extreme end of the plate 15 is a slot 25 in which is positioned a screw 26 threaded to the under plate 14. Between r .the threaded member 26 and the pivot/mom ber 16 the upper plate 25 is provided with upper plate '15 will be raised and lowered therewith. As the plate 15 is adjusted vertically in relation to the under plate 14; the forward end of said plate'15 is adapted to slide upon the under plate 14 and accommodate itself to its adjusted position, the members 28 moving lengthwise of the slots 27 during this adjustment. I 1

At the forward end of the slots 27 the flange 31 is cutaway as at 32 so that the head of the member 28 may be removed from the slot 27 when desired. The inner sole 13 is cut through at various points to form tabs 33 which normally rest upon the adjusting members 28, but they may be" lifted up into the position indicated at 341 to permit a screw driver to be inserted in the slot of the members 28 to turn said mem-' It is a well-known fact that Where shank *supports are required the user must be gradually accustomed to the curvature of the shank support required to correct the particular condition of his feet. Where the required curvature to the shank is given at once it often occurs that the pain is such that the individual wearing the shoe is made very uncomfortable and cannot endure the pain for any length of time. This is a great objection, and by means of the construction herein shown this condition is obviated as the shank support may first be adjusted with very little curvature to the shank support, and as the wearer gradually becomes used to the curvature glven, the curvature may be increased day after day until the required amount is finally secured.

. Another advantagerof the device is that the same shank supporter may be adjusted for use by different individuals whose feet require varying degrees of curvature of the supportingplate. In some cases it is desirable to raise that portion of the plates 14 and 15 immediately over the front inner end of the heel 12 and this may be accomplished by turning the pivot 16 in its socket or flanged member 17 It is believed that the many advantages of a shoe of this construction will be fully apparent from the foregoing description.

Having thus described my Invention, I

claim:

1. In adevice of the class described, the combination of two plates pivoted at one point to the sole of a shoe and movable togetherabout said pivotal point; and adjustmg members interposed between said plates adapted to separate them predetermined disv tances.

2. In a device of the class described, the

" combination of two plates held together at two points; a pivot member extending through both plates and secured to the sole of a shoe; and adjusting members interposed betweenfsaid plates between said points and'adapted to separate them predetermined distances.

3. In a dev 1ce of the class described, the

combination of two platesheld together 'near one end; a stud near the other end thereof adapted to retain said plates in contact; a socket for said stud in the outer sole of a shoe; means whereby said stud may be adjusted relatively to said socket; and means for separating said plates predetermined distances between said stud and the free ends of said plates. v

4, Ina device of the class described, the

combinatiorr of two plates held together near one end,- a stud near the other end".

thereof adapted to retain said plates in contact; a socket for said stud in the outer sole of a shoe; means whereby said stud may be adjusted relatively to saidsocket; and means positioned near the inner edge ofsaid plates for separating said plates predetermined distances etween said stud and the free ends of said plates. f i

5. In a device of the class described, the combination of two plates secured together near one end, one of said plates having a ings; a rivet in the other plate extending through said slot; and adjusting, members intermediate the ends of said plates for separating them predetermined distances,-

said adjusting members having shoulders beneath the openingsin the upper plate and being threaded to the lower plate.
